Monopolies stimulate capitalism

The argument

Supernormal profits lead to new entrants in industries and the desire to get rich. In many industries, the first mover may enjoy the benefits of coming up with a profitable idea. The lure of profits will drive others to enter later. Without monopoly type profits, there would be little incentive to innovate. In some cases, this initial monopoly is driven by patents/copyrights. Society has chosen to reward patents for centuries in order to motivate inventors to innovate. Research and development is costly and uncertain. Monopoly profits are a just reward for innovation.

Premises

Counter-arguments

Critics reply that the argument conflates the temporary reward for innovation with entrenched monopoly, and that once established, monopolies tend to suppress the very dynamism the argument credits them with. The prospect of profit does spur innovation, but that is an argument for time-limited patents and competitive markets, not for durable monopoly; a firm that has captured a market has reduced incentive to keep innovating and strong incentives to block entrants, raise prices and buy up rivals. Economists note that sustained monopoly can slow innovation and misallocate resources, which is why competition law exists. The reward-for-innovation point, they argue, justifies patents, not monopoly as a lasting condition.

Rejecting the premises

[Rejecting P1] Innovation needs the prospect of reward, but that is supplied by time-limited patents and the chance of profit in competitive markets, not by durable monopoly. [Rejecting P2] Once a monopoly is entrenched, it has weaker incentives to keep innovating and strong incentives to block entrants and raise prices, undercutting the dynamism claimed. [Rejecting C] Because lasting monopoly can suppress innovation and misallocate resources, the reward-for-innovation point supports patents, not the conclusion that monopolies are good for the economy.
